Bill Walsh, who coached the San Francisco 49ers to three Super Bowl championships in the 1980s and became one of professional football’s most influential figures, devising passing strategies that were emulated long after the decline of his dynasty, died yesterday at his home in Woodside, Calif. He was 75.

The cause was leukemia, the 49ers said. Walsh disclosed last November that he was being treated for leukemia, which had been diagnosed two years earlier.

Except for high school coaching, Walsh did not become a head coach until Stanford hired him when he was 45. And he spent 11 seasons as an assistant in the N.F.L.

But his long apprenticeship — too long, the way he saw it — served him well. He honed his creativity and became known as “the genius,” a silver-haired, almost professorial presence orchestrating the 49ers’ brilliant offenses as the head coach from 1979 to 1988.

Walsh had a regular-season record of 92-59-1 with the 49ers, serving as offensive coordinator in addition to head coach and, at varying times, as the general manager and the club president. His lineups featured the future Hall of Famers Joe Montana at quarterback and Ronnie Lott at defensive back and the league’s career receiving leader, Jerry Rice. Walsh was elected to the Pro Football Hall of Fame in 1993.

Walsh’s playbooks bulged, focusing on a passing game that became known as the West Coast offense. It featured mostly short or medium-range passes designed to work against all types of defenses, and it included trick plays. His was a horizontal offense, in contrast to the vertical strategy that depended on long — and low percentage — passes downfield. Walsh’s offense became the aerial equivalent of a ball-control strategy previously associated with a running game.

“When we go over the game plan during the week, it doesn’t look like it will work,” Montana told Dave Anderson of The New York Times shortly after the 49ers defeated the Cincinnati Bengals to win the Super Bowl for the first time. “But when we get into the game and use it, it seems that the plan always works.”

Walsh’s pass patterns generally succeeded in getting at least one receiver open and sometimes as many as three.

He cited several factors for his extraordinary success.

“I think we’re willing to settle for a little less yardage on passes than some teams are,” he said after the first Super Bowl triumph. “Two, our willingness to throw to the second and third receivers. And three, to look downfield for the great individual play.”

Walsh proved influential on matters beyond his passing game. He was an early advocate of minority hiring for coaching positions, many of his assistants became head coaches, and his procedures in organizing a team and developing practice routines were copied.

William Ernest Walsh, a native of Los Angeles, played wide receiver and boxed at San Jose State. After coaching in high school, he became an assistant at the University of California and at Stanford, then embarked on his pro career in 1966 as an assistant with the Oakland Raiders.

He moved to the expansion Cincinnati Bengals in 1968 as an assistant to the head coach and owner, Paul Brown, and developed Ken Anderson into an outstanding quarterback. When Brown retired and passed him over for the head-coaching spot in 1976, in favor of the offensive line coach Bill Johnson, Walsh joined the San Diego Chargers as the offensive coordinator and tutored quarterback Dan Fouts.

Walsh returned to the college ranks as Stanford’s coach in 1977 and 1978, taking the team to bowl games each season and developing Guy Benjamin and Steve Dils into star passers.

When Walsh became the 49ers’ coach in 1979, he took over a team that had gone 2-14 the previous season.

The 49ers were 2-14 again in Walsh’s first year, but he gradually built a championship squad.

A signature play came in the 1982 National Football Conference championship game against the Dallas Cowboys, when Montana rolled out and threw a 6-yard touchdown pass to Dwight Clark at the back of the end zone in the final minute.

Shortly after the 49ers won the 1989 Super Bowl, Walsh stepped down as the coach and became the team’s executive vice president for football operations. But in July ’89, he left to become a football broadcaster for NBC. His successor, George Seifert, who had been the 49ers’ defensive coordinator, went on to win two Super Bowls with San Francisco.

Walsh had a second tenure as Stanford’s coach, from 1992 to 1994. He returned to the 49ers as the vice president and general manager from 1999 to 2001, was later a consultant to the team and served as Stanford’s interim athletic director in 2005-6.

He is survived by his wife, Geri; a son, Craig of Redwood City, Calif; a daughter, Elizabeth of San Francisco; a sister, Maureen of Mission Viejo, Calif; and two grandchildren.

Walsh regarded football as something beyond a test of physical will.

“If I have any talent, it’s in the artistic end of football,” he once told Lowell Cohn of The San Francisco Chronicle.

“The variation of movement of 11 players and the orchestration of that facet of football is beautiful to me.”
